CORNER-FASTENING FOR METALLIC BEDSTEADS.

SPECIFICATION forming part of Letters Patent No. 773,283, dated October25, 1904.

Application filed. May 20, 1904. Serial No. 208,856. (No model.)

To all ZU7L0771/ it may concern:

Be it known that I, J ESSE P. FULGHAM, a citizen of the United States,residing at Rich-. mond, in the county of WVayne and State of Indiana,have invented certain new and useful Improvements in Corner-Fasteningsfor Metallic Bedsteads; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, and tothe letters of reference marked thereon.

This invention relates to improvements in corner fastenings or couplingsfor metallic bedsteads by means of which the side rails may bedetachably secured to the corner-posts; and it has for the object toprovide a coupling which shall be simplein construction and readilysecured in position.

To these ends the invention consists in certain novel details ofconstruction and combinations and arrangements of parts, all as will benow described, and the particular features of novelty pointed out in theappended claims.

Referring to the drawings, wherein is illustrated the preferredembodiment of the invention, Figure 1 is a side elevation of thecoupling. Fig. 2 is a top plan view of the corner-post member of thecoupling. Fig. 3 is a detail view looking at the interior of the partsconstituting the corner-post member of coupling, said parts beingseparated. Fig. 4 is a perspective view of the rail member. Fig. 5 isaside elevation of the same. Fig,- 6 is a horizontal sectional view online 00 m of Fig. 1. Figs. 7 and 8 are views of a modified constructionof the post-section of the coupling.

Similar letters of reference in the several figures indicate the sameparts.

In the drawings, the letter A indicates one of the corner-posts of ametallic bedstead, which may be of any desired form or configuration,but is preferably circular in crosssection.

The corner-post member of the coupling consists, preferably, of twocastings B and C, each of which is cast with a semicircular recess b 0,whereby the castings may be fitted about the corner-post of thebedstead. At

'member of the coupling.

the rear one of these castings, as B, is provided with an opening 6',with which cooperates a lug 0 on the other casting, thus constituting ahinge connection between the castings, as will be readily understood.The castings when in place upon the corner-post may be secured by meansof a bolt D. In the forward portion of the casting C and on the insidethereof is formed a recess. 0 one wall, of which is straight and theother, 0", inclined from top to bottom, thereby forming a recess whichdiminishes in width toward the bottom, as shown clearly in Fig. 3.Beyond this recess the casting is extended, as at c, and is formed witha flat inner face, which bears against the rail-casting when in place,as will be presently explained. The cooperating casting B does notextend as farforward as the casting C and is formed with a projection Z2extending at a right angle to the main portion of the casting and havinga flat face, which face extends slightly beyond the Straight wall 0 ofthe recess in the other casting, C. The inner edge of the flat face 6 iscut away, forming a shoulder 6 as shown.

Secured to each side rail of the bedstead is a casting or head formingthe cooperating As shown, this head has a central body portion E,through which securing-bolts 6 pass for securing the head upon the rail.Fxtending upwardly and downwardly from the forward end of said. centralportion E are the arms a a, curved at the upper ends at substantiallyright angles, as at e 0 the inner faces of said portions being curved tofit the corner-post, as shown in Fig. 1. On its inner face the castingor head is formed with a lug, a projection 0 having anoppositelyinclined face (2*, and at the front of the body portion Ethere is a projection 0 extending at right angles to the body portionhaving a flat face, which is adapted to bear against the fiat face ofthe projection b on the casting B, as shown in Fig. 6. The lug orprojection e" is of such a width that when in the recess 0 its rear edgedoes not engage the straight wall 0 of the recess.

Formed on the front face of the body portion E ofthe rail-casting on theside opposite to the projection c is a rib or projection e,

which constitutes a locking projection which cooperates with theshoulder 7)" on the casting B, as shown in Fig. 6.

With the castings constituting the eouplings secured to their respectiveparts all that is necessary to couple the rail to the cornerposts is toinsert the lug c on the rail-casting or coupling-head in the recess inthe casting 0 and then by a downward pressure the inclined wall of thelug will be caused to engage the inclined wall of the recess, thusdrawing the coupling members together and bringing the flat faces of theprojections 6 and a" into contact and pressing the curved end portionsof the arms a 0 against the corner-post. As the lug a" does not contactagainst the straight wall of the .recess 0 there are but three points ofcontact-namely, the flat faces 6 and and the ends of the arms againstthe corner-post.

Lateral movement between the coupling members is prevented by means ofthe interlocking shoulders e and If, the parts being also braced by theextended portion 0 of the casting C bearing against the rail-casting,all as will be readily understood from an inspection of Fig. 6.

By having the lug a on the rail-casting formed with double inclines thiscasting may be used at either end of the rail and the corner-postcastings may be used on either post by simply casting the recess 0 inthe casting C, with the wall c inclined in opposite directions.

Instead of making the corner-post coupling member in two parts it may bemade in one piece, such a construction being illustrated in Figs. 7 and8. In this construction the coupling is made of malleable iron, the twoparts being connected by a web F, which is bent around the corner-post,as shown in Fig. 8, and secured in place by bolts, as in the other form.In other respects the construction is the same as in the other form ofthe device.

lt will be seen that the coupling can be readily secured in place andthat the rail may be easily uncoupled or coupled to the cornerpost.

The coupling consists of few parts and can be cheaply manufactured.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is"

1. In a corner-coupling for metallic bedsteads, the combination with thepost member consisting of a single piece of metal having at each end aportion of the coupling-head, one of said portions formed with a recesson its inner face and the other with a flat face extending substantiallyat right angles to the first portion opposite said recess; anintermediate web connecting said portions, adapted to be wrapped aboutthe corner-post, whereby sai-l coupling portions will be brought intoposition to complete the head, and the cooperating coupling membercarried by the rail; substantially as described.

2. In a corner-coupling for metallic bedsteads, the combination with thecoupling member carried by the post, provided with a recess, and havinga lateral projection opposite the recess formed with a fiat face, of therail member provided with a lug cooperating with the recess in the postmember to lock the members together, and having a lateral projectionhaving a flat face, adapted to contact with the lateral projection, onthe post mem her, and the arms on the rail member adapted to bearagainst the corner-post; substantially as described.

3. In a corner-coupling for metallic bedsteads, the combination with thecoupling member carried by the post, having the recess therein, of thelateral projection thereon, having a flat face, formed with a shoulder,the rail member having a lug cooperating with the recess in the postmember, the lateral projection, adapted to bear against the lateralprojection on the post member, the projection on the front of the railmember, adapted to engage the shoulder on the lateral projection of thepost member, whereby the coupling member will be held from lateralmovement; substantially as described.

4. In a corner-coupling for metallic bedsteads, the combination with thepost member formed of malleable iron, and consisting of two cooperatingsections, one formed with a recess on its inner face and the othersection formed with a flat face extending substantially at right anglesto the other section and lying opposite said recess, the connecting-web,and the cooperating rail member; substantially as described.
